Description

As of March 1, 2024, FleetSSL cPanel has shut down, bringing their repository offline and preventing package managers from pulling the repomod.xml file. The third-party FleetSSL cPanel Let's Encrypt plugin must be removed and replaced with the cPanel-provided Let's Encrypt plugin.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the following command to uninstall the FleetSSL cPanel-provided plugin.
   • CentOS 7 and CloudLinux 6/7

     yum remove letsencrypt-cpanel

   • CloudLinux 8/9, AlmaLinux 8/9, Rocky Linux 8/9

     dnf remove letsencrypt-cpanel

3. Remove the old FleetSSL repository file.

   /usr/local/cpanel/scripts/autorepair disable_dead_fleetssl_repo

4. Rebuild the package database.
   • CentOS 7 and CloudLinux 6/7

     yum clean all

     yum makecache

   • CloudLinux 8/9, AlmaLinux 8/9, Rocky Linux 8/9

     dnf clean all

     dnf makecache

5. Run the following command to install the cPanel plugin.
   • cPanel version 116 and earlier

     /usr/local/cpanel/scripts/install_lets_encrypt_autossl_provider

   • cPanel version 118+ on RHEL-based systems

     dnf install cpanel-letsencrypt-v2

6. Access WHM as the root user, and navigate to "SSL/TLS / Manage AutoSSL" to select your provider.
